parentesi oet. sa, raie..

To all whom t may concern Be it known that I, ALBERT D. GRovnR, a citizen oi' the United States, and a resident of Malden, in the county of Middlesexl and State of Massachusetts, have invented certain new and useful Improvements in Vencling-li/Iachines, ot' which the following' is a specification.

My invention relates to vending machines and has for its object in general the provision of a machine particularly adapted for use in locations where space is very limitedas for instance in street cars or .railway cars, where it can be readily attached to the wall or posts between the windows. In other words. the machine of my invention is desiOned to take up as little room as possible and will not project sui'liciently from its support to be considered an obstruction. Ina inachine which l have actually constructed in accordance with the invention herein disclosed, the depth ot the machine casing was about three fourths ot an inch, and the width about two and one halt inches. The height oit course will depend upon the number of packages (such as chewing' gum, candy and the like) which the magazine shall contain. In order to reduce the depth of the machine to a minimum, I provide a magazine adapted to contain the vendible articles edge upon edge in a vertical column which rests upon an adjustable supporting' mechanism operable to release the articles one by one. In the broad aspect of my invention, this supportinai mechanism has upper and lower supportine portions movable with respect to each other. so that before one portion can pass fully into releasing` position. the other portion reaches a supporting' position. This absolutely insures the vrelease of the articles one by one. With this supporting' mechanism, no separate eiecting' device is necessarv` which adds greatly to the compactness of the machine.

More specifically considered, my new form ot supporting' and releasing' mechanism comprises two pairs of oppositely arranged levers at the lower end ot the magazine. Normally. the column of articles rests upon the two lower levers. These are so connected with the upper levers that before the lower levers move out of supporting position` the upper levers engage the column of articles above the lowermost article and support the entire column as lona as the lower,

levers are in releasing position.' Not until the lower levers have reached their normal or supporting position, do the upper levers release the column oi" articles and allow the same to drop on to the lower levers for support. rIhe levers of the supportingl mechanism are .operated by means of a coin-controlled slide which is vertically movable and operated from the outside of the machine by any suitable means-such as a knob or wheel. rlhis slide is normally locked against full movement, but is unlocked through the medium of the deposited coin. When the last package has been discharged from the magazine, the slide is automatically locked in its lowe 'most position to prevent the insertion of a coin into the machine.

rihe above and other obiects and advantages of mv invention will become apparent from a detailed description ot' the dra wings 'I which show a machine embodying the various features of my invention in a form now best known to me.

In these drawings, Figure l, is a front view of the machine, with the front wall of the casina` broken away in order to expose the interior mechanism to View. Fie: 2. is a longitudinal section on line 2-2 of Fig. 1. Fig. 3. shows a view similar to Fig. l, with the coin slide and the supporting mechanism in operated position. Fig. il. shows a horizontal section substantially on line 4--t of Fig. 1. Fie'. 5, is a vertical detailed section on line 5 5 ot Fig', 3. showing` the coin slide in locked position when the magazine isempty; and Fig. 6, is a vertical detailed section of a portion of the machine showing; the slide locked against movement by a deposited washer.

The casing of the machine is preferably formed of two sections-a rear section comprising a plate l. and a front section comprisinsz the front wall 2, sides 3 and 4. top 5 and bottom G. The two sections are secured tocether in anv convenient wav. In the drawings I have shown the baclrplate l provided with side flanges 7 'for receiving the sides 3 and il. as shown in Fin. Ll. and with a bottom i'lanae S which provides a recess 9 for receiving the flange 10 on the bottom plate G. The front section of the casina1 is held locked against the back plate 1 by a suitable lock 11 of which the bolt l2 engages the cross har 13 secured to the back pla+e l at the points 14.

The back plate 1, means of which the. machine is adapted to be secured in place on.

vso

any desired support, carries the magazine containing the vendible articles. This magazine may be conveniently formed of a pair of sheet metal bars 15, having rear flanges 16 for receiving suitable fastening devices, and front ianges 17 for retaining the packages within the magazine. As seen from Figs. 2 and 1, the depth of the magazine is very slight, so as to retain the articles or packages P edge upon edge in a vertical column. These packages P may contain any suitable confectionssuch as chewing gum or candy. The height of the machine would vary in accordance with the capacity of the magazine.

I have provided a novel mechanism for supporting the packages in the magazine and releasing them one by one, without dan-y ger o f more than one package being released-'at each operation of the machine. Broadly speaking, this mechanism has two separate and distinctive engaging portions, one for supporting packages when the mechanism is in normal position, and the other for supporting the packages' when the mechanism is in operated position. These engaging portions are movable relatively to each other, so that one portion passes into engaging position before `the other portion reaches a releasing position. In this way the column of packages is never without a positive support.

Referring now in Vdetail to the specific form of supporting and releasingmeehanism shown in the drawings, it will be seen that I have provided a pair of lower levers 18 and a pair of upper levers 19. Each pair of levers 18 and 19 is pivotally mounted on a pin or stud 2O carried by the back plate 1. The two pairs of levers are mounted upon opposite sides of the package magazine at the lower end thereof, and are so arranged that when the levers 18 are in normal position, the lowermost package P rests at its ends directly upon the supporting lugs 21 which project inwardly from the levers 18. These levers are held in normal position by spring blades 22 secured to the sides of the casing at 28 and adapted at their free ends to bear against the pins 24 projecting laterally from the levers 18. Any other suitable arrangement may of course be provided for holding the levers 18 in normal position. The upper levers 19 are yieldably connected with their respective lower levers 18 by means of springs 25. The upper end of each of thesesprings is connected to the upper lever 19 and the lower end to the lower lever 18, while the intermediate portion of the spring is coiled about thek pivoted stud 20. The function of the springs 25 is to hold the levers extended as shown in Fig. l, so that each pai-r of levers moves through a certain angle as one member; This movement of each pair of levers asa uiiit is limited by the pins 26 at the upper ends of the levers 18 engaging in the slots 27 formed in the upper levers 19. At their free ends, the levers 19 are provided with pointedA projections 28. The connection between the levers 18 and 19 is such that when the levers 18 are in supporting position, the pointed projections 28l on the levers 19 are out of the magazine. However, when thel levers 18 are moved outwardly by means to be presently described) into releasing position, the levers 19 are rocked inwardly and the pointed projections 28 enter the magazine and pierce the sides of the package above the lowerinost one suiiiciently to support that package and all the packages above it. Fig. 3 clearly shows the levers 18 and 19 in operated position. The movement of the levers 18 and 19 with respect to each other is so timed, that before the supporting lugs 21 of the levers 18 have moved out of contactwith the lowermost package, the pointed projections 28 on the levers 19 have firmly engaged the package above the lowermost one, and thus support the entire column while the released package falls out of the magazine, through the delivery-chute 29 into the pocket or delivery-opening 30. In'Figs. 1 and 2, the delivered package is shown at P1. To enable the package to be readily grasped by the patron, `the front wall of the casing is cut away at 31 and 32. It will be noticed that the packages are delivered end-on. rIhe chute 29 and the delivery pocket 30 are formed by a partition 33 suita blv secured to the front section of the casing. Vhen the springs 22 return the levers 18 to normal position. the levers 19 remain in operated or retaining position until the pins 26 strike the outer ends of the slots 27. lVhen this occurs, however, the lugs 21 of the lower levers 18 have already moved into supporting position, so that when the continued movement of the levers 18 rocks the levers 19 out of retaining position, the released column of packages drops on to the lugs 21. By this means it is impossible for more than one package to be delivered at each operation of the machine. This is one of the most important features of my invention. The supporting and releasing devices on the escapement principle which have heretofore been attempted, have been found to be absolutely inoperative, in that they failed to support the articles in the magazine after the delivery of the released article and upon return of the parts to normal position. In my new form of supporting and releasing mechanism. the relative movement of the levers 18 and 19 always insures the movement of the upper levers 19 into supporting position before the lower levers 18 reach a releasing position, and vice versa..

The levers 18 are moved outwardly into releasing., position by means ofl the coin l l il llt;

slide which is mounted in the front section ot the casing for vertical reciprocation. The lower corners ot the coin-slide 34 are beveled, as shown at 35. From the lugs 21 on the levers 18 project forwardly the extensions 36 which are arranged to be engaged by the beveled portions of the coin-slide as the latter is moved downwardly. In this way the levers 18 are rocked outwardly from supporting into releasing position upon a complete downward movement 01:'-

the coin-slide 34. T his slide is guided in its movement by the plate 37 suitably rsecured to the front wall ot' the casing.

Complete downward movement of the coin-slide 34 is normally prevented by the pins 38 carried at the upper ends of the two levers 39 which are pivoted on pins 40 secured to the guide plate 37. The pins 38 are at their outer ends semi-cylindrical, as clearly shown in Fig. 1, and project into the slots 41 formed in the coin-slide 34 on opposite sides of the projection 42. rlhe coin-slide is also provided with a downwardly extending projection 43 having a curved recess 44 which coperates with the curved end 45 of the projection 42 to form the opening 46 for receiving the deposited coin. On either side of the recess 44 are provided stop shoulders 47 which are arranged to encounter the pins 38 when the slide is pushed down. The levers 39 are held inwardly by the springs 48 secured at their upper ends to lugs 49 mounted on the front section of the casing. Stops 50 are arranged to limit the inward movement of the levers 39. The normally free movement ot the coin-slide 34 is insuiiicient to bring the beveled corners 35 into engagement with the extensions 36 on the levers 18. However, when a proper coin is deposited in the coinreceiving opening 46, and the coin-slide is thereupon operated downwardly (through connections to be presently described), the coin engages the pins 38 and forces them outwardly into vertical alinement with the slots 51 formed at either side of the projection 43. With the pins 38 in this position, the coin-slide 34 is tree to move downwardly until the pins 38 engage the upper ends of the slots 51. In other words, the function of the deposited coin is to move the locking pins 38 out of the path of the stop shoulders 47, and thereby allow the coin-slide to have full ejecting movement. ln the broader aspect of my invention the slots 41 and 51 may be considered as portions ot a single slot. As already described, when the coin-slide is moved downwardly to its fullest extent, the beveled corners 35 engage the extensions 36 of the goods-supporting levers 18 and force the same apart outwardlv to release the lowermost package which falls into the pocket 30 through the chute 29. rlhe :trontplate 2 oit the machine casing is provided with a coin-entrance opening 52 which registers with the coinreceiving opening 46 on the coin-slide 34 when the latter is in normal position.

It should be noted that the coin-engaging pins 38 also serve as a coin-testing device. For instance, it' the deposited coin is of insutiicient diameter, the pins 38 will not'be forced outwardly a suiiicient amount to clear the shoulders 47. Should the deposited check be of soit or 'yieldable material, such as lead, paper and the like, the edges of the semi-cylindrical pins 38 will bite into the material of the check and thereby act as a positive stop against the further downward movement of the coinslide.

Preferably, the opening 52 is surrounded by an inwardly extending flange 53 which coperates with the iixed plate 37 to guide the coin-slide 34 in its movement.

The coin-slide 34 has rigidly attached thereto a rack 54 arranged to mesh with the pinion 55 fixed to the inner end of the stub shaft This shaft projects to the outside or' the machine through an opening in the front panel 2 and is at its outer end provided with a suitable hand-operated member-such as a wheel or knob 57. It is evident that when the knob 57 is rotated in a clockwise direction, the coin-slide 34 is moved downwardly through the rack and pinion connection just described. Fig. 1 shows the coin slide in upper or normal position, while Fig. 3 shows the same in lower-most or operated position. The coinslide is returned to normal position by suitable spring means-such as a contractile spring 58 which is secured to the coin-slide at 59 and to the casing at 60.

On top of the column of goods in the magazine rests a. weight 61 provided with a pair of beveled projections 62, as best shown in Fig. 4. Really only one proiection would be necessary, but by providing one on each side, the weight may be inditterently inserted into the magazine. The guide plate 37 is at its lower end provided with a recess 63 :From which extends upwardly the slot 64. This slot and recess serve to accommodate the dog 65 which is pivoted on the pin 66 carried by the guide plate 37 at the recess 63. A spring 67 coiled about the pin or stud G6, engages at its upper end the pin 6,8 carried by the dog 65 and at its lower end bears against the guide plate 37 to hold the dog 65 normally in backward position, as shown in Fig. 2. At its tree end, the dog 65 is provided with a projection 69 having an upwardly extending point 70. This point is adapted to engage the beveled upper end 71 of the slot 64 to limit the rearward movement of the dog 65 under the influence of the spring 67.

When the last piece ot goods drops out of the magazine, one of the projections 62 on the weight 61 comes in contact with the dog 65k and forces the same forwardly into the positionV shown in Fig. 5. It should be understood that this forward movement of the dog 65 takes place when the coin-slide 34 is in lowermost position, so that the nose or projection 69 of the dog engages the shoulder 72 on the coin-slide. This positively locksv the coin-slide in lowermost position, and prevents the deposition of further coins into the machine. Preferably, the coin-slide carries a suitable sign or mark such as the word Empty7 Vwhich registers with the coin-opening 52 of the front plate when the machine is empty, to inform the patron of that fact. To unlock the coinslide, it is necessary to remove the frontsection 'of the machine and restore the dog 65 to normal position by hand, whereupon the coin-slide is drawn upwardly into normal position by the spring 58. After'the magazine has been filled with the desired goods, the weight 61 is placed on top of the packages, and the front section of the casing locked in place again, whereupon the machine is ready for operation as before. The weight 6l is at its sides provided with grooves 7 3 to accommodate the points 28 of the levers 19.

In order to prevent the machine from being operated by washers, I provide a pawl 74 pivoted at 75 to the guide plate 37 and provided at its lower end with a forwardly projectinghook 76 arranged to extend through the opening` 7 7 in the guide plate. A leaf spring 78` fixed to the guide plate 37, at the points 79, bears at its lower end against the shoulder S0 formed at the upper end of the pawl 74, to force the hook 76 forwardly. rIhe pawl 74 is pivoted substantially midway of the guide plate 37, as best shown in Fig. 4, and is readily accommodated in the space between the guide plate and the magazine. When a washer isideposited in the coin-receiving opening 46 and theknob rotated to move the coin-slide 34 downwardly. the hook 76 of the pawl 74 enters the opening inthe washer before the Slide is moved downwardly anv great eX- tent, Yand thereby positively locks the slide yaga'instvfurther downward movement. Fig.

6, shows howthe hook 76 of the pawl 74 has entered the opening in the washer 8l. lVhen the knob 57 is released, the coin-slide 84 is carried back to its normal position, together with the deposited washer. This movement is permitted by reason of the fact that the hook 76 is beveled at the bottom,

so vthat it is cammed rearwardly by the washer during` the'return movement of the coin-slide. The washer is therefore carried back-to the coin-opening where it can be removed. -The pawl -74 serves another purpose, Yand :that is4 toeject v.the A coin from `the coin-slide into the passage 82 whence it falls into the coin-box S3 su tably secured to the front panel 2 of the casing. lVhen the coinslide 34 carries a good coin, the hook 76 of the pawl 74 presses against the same and as soon as the coin-slide 34 is moved down suliiciently for the upper edge of the coin to clear the shoulder S4 provided on the front plate below the coin-opening 52, the coin is forced out of the Coin-slot 46 by the hook 76 and drops into the cash box S3. This ejection of the coin by the pawl 74 does not-'take place until after the pins 38 have entered the slots 5l in the coin-slide 34.

The operation of my new machine will be clearly understood from the foregoing detailed description, and it is not therefore believed necessary to repeat the same.

Although I have described one specific form of machine embodying the various features of my invention, I would have it understood that I do not intend to be limited to the details of construction set forth, as it is obvious that various changes and modifications may be made without departing from the scope of the invention as defined in the appended claims.

Owing to an oliicial requirement for division, the claims in this case are confined to the coin-controlled features of applicants invention. The other features-namely, those relating to the delivery mechanism and associated parts, are the subject-matter of applicants eo-pending application, Serial No. 30,045, iiled May 24, 1015.
